jrse commented 2 years ago

if append gets interrupted, imap process fails with panic: file mail-index-transaction-update.c: line 345 (mail_index_expunge_last_append): assertion failed: (seq == t->last_new_seq)

in case of abort, the ostream was not correctly closed
in case of abort, the index entry only need to be removed if already written to the index.
